Zedomax DIY - How to Make a Simple Green Laser Projector!

Since I have been playing with green lasers for about a year, I never saw any good use for them except to point them to the sky or buildings.
Since the green laser has a lot of power, especially the one DragonLasers sent me recently, I decided it was time to make a simple green laser projector without me spending days to build one.
This simpler green laser projector was made so I could use it for my next party and I always wanted to make this. Although this laser projector only does one animation, 2 whirpools, I planned to improve upon after making this very basic version.

When the motor is stopped, it also displays a bunch of green laser stars like this:

Step 1
First, you will need a green laser. I recommend anything 125mW and above.
For this DIY, Frank from DragonLasers.com sponsored me a Spartan 250mW green laser. (Thanks Frank!)
You also need a diffractive glass that will distribute the green laser beams. I was lucky that the Spartan comes with it. You could probably use those cheap diffractive glasses from 3D glasses too.
Second, you will need a plastic epoxy. (In the video, I say you need two but you just really need the plastic epoxy as it works really good for everything.)
Third, you need bunch of pipes. I went to home depot and got bunch of cheap galvanized pipes for about $10 total.
Step 2
You need to drill a hole in the center of the diffractive glass, then epoxy it to the motor. Now, I accidently broke the glass and had to epoxy everything. Just make sure to use a real thin drill and go slow so you don’t make the same mistakes that I did.
Then, also epoxy the bottom end of the motor to the 90 degree pipe arm. (Make sure to solder on 2 wires to the motor!)
(Sorry, I forgot to take pictures while doing that…)
Step 3
Build your green laser projector using the pipes and pipe parts sorta like below.
Put all the wires through the pipes so it comes out the other end. (Sorry again, I forgot to take pictures of this step…) Then assemble everything. You can fit the green laser through the T-pipe piece. (For the T-pipe piece, I used a bigger size then used electrical tape around the pipes to stabilize it.)
Step 4
Now you have two wires coming out the other side of pipe. Simply connect that to a 1.5V battery OR you can use a DC adaptor.
Step 5
Once you get the motor running, simply align your green laser and there you go, a simple green laser projector.
You should get nice set of two whirpools of green laser beams.
Now, you could probably add another axis and another motor to get even better animated effects.
I plan to add a microcontroller like CUBLOC or Basic Stamp in the future so stay tuned and subscribe to Zedomax.com.
This DIY was made to experiment with the green laser, so don’t shoot me if it’s not super high tech. It’s supposed to be simple enough so any regular joe can make one. But I promise next time it will be more high tech…

Hi all,
This is a special review of giant green lasers on the market today.
Since I was getting tired of my little measly 125mW green laser from DragonLasers, I was going to go on shopping for a super-giagantic laser that will fulfill my dreams. (So I can burn stuff from miles away from my 12th floor apartment without getting caught…)

Check out these really cool high power green laser pointers. Although the cost of each is like
couple bills, they can do wonders for your next light saber project. Thanks Smitty for the info!
Will dragonlasers send us a sample so we can build a light saber? :]
Smitty says, ” Been checking out laser pointer websites so i can buy my first pointer and found www.dragonlasers.com They look the same as wicked’s but the prices are MUCH lower. All i need now is my dads credit card lol”
The color of a laser bea\m is determined by the wavelength of the light given out by the laser diode in the laser pointer. Our laser pointers ONLY give out green light. Green light is the most visible color to the human eye. This makes the beam from our laser pointers very bright with a spectacular vivid green color. Shoddy green laser pointers on the other hand do not just give out green light, they also give out infrared light. Infrared light cannot be seen by the human eye so the beam from these shoddy laser pointers is not as bright as it should be and is also very dangerous. You may be asking why a shoddy laser pointer can have a power of 200mW but be less bright than a 50mW dragonlaser. Here is the trick. As we just said, these laser pointers give out a lot of infrared light which you can’t see making them less bright. Laser power meters however cannot distinguish between green light and infrared light. The 200mW power level of a shoddy laser pointer will normally be made up of mostly infrared light. For example a combination 25mW green (532nm) and 175mW infrared (808nm). A 50mW dragonlaser will be 50mW green with virtually no infrared.
